Blender 2.8 Beginner Tutorial - Part 7: Texture Painting


– [Zach]. Welcome to the seventh part of the Blender. 2.8 Beginner’s Tutorial Series. In this video, we will texture, paint, the apple and the knife using images which we project paint onto the objects. So we’ve got realistic textures for our materials later on. As always, you can find the timestamps in the video description below, And if you want to follow along, sign up to our resource section free of charge There, you can download all the project files, textures and our handy. Blender, 2.8 shortcut PDF. Hi, everyone, Zach. Here for CGBoostcom. And let’s get started. So let’s start with the texture painting process of the knife. And let’s start with the handle. First of all, let’s select the blade here and hide this. Instead of using the eye here, you can also simply press H to hide this. Let’s select the handle and for texture painting, simply click on the texture painting workspace. As you can see, this turns pinkish and pinkish means always that there is basically no texture attached to it. So as you can see right now, we are automatically switched to texture paint mode. And over here, we have not the UV Editor. This is as you can see the image editor. Both looks pretty similar bit over here. We, for example, have the paint mode enabled. Then, in order to be able to draw on an object, we need a plane image as foundation to draw on. In order to add this, we simply click on the new button over here. Then this window pops up. Let’s simply call this knife paint. Then let’s change the resolution to 2048. X 2048. Which is basically a 2K resolution. This is quite high for a simple object like the knife. But if we start with a high resolution later on, we can reduce the resolution of the image anyway. Then we can define a base color. So for this, let’s simply use something similar as the handle something like this. But in the end, this doesn’t matter because we paint over all the important areas anyway. Then simply click, okay. Let’s zoom back a bit. Now you can see this image was generated. As soon as we add an image here, this doesn’t mean that this is also connected with the 3D model as you can see. In order to do that, you have to go to this tab over here. And under texture slots, the mode right now change this to single image. And over here, we don’t want to create a new image. We simply pick the image we already have. So let’s click on this little image icon and use the knife paint. Then this image will be connected to the handle over here. Then we can start to paint on this. But we don’t want to paint this by hand. So basically, I just could start painting over here. And then you can see how the pixels of the image will be colored, depending on what I do. Down here, if I collapse this, we have all the important settings for the texture painting. For example, we have the brush over here with a radius we can change. You can see it on the circle in the 3D viewport. But to change this, we can also press. F move our mouse and confirm with left click. You can see the radius over here will change as well and this way. We don’t always need to move our mouse over here if we quickly wanna change the size of the brush. Then very important since we will now project an image onto the object over here, we need the full strength because right now it’s basically just painting with 70%. So let’s set this to one. And now let’s add an image we can use for painting. For that, let’s go down here to the texture tab. Create a new image, lets. Call this knife. Click on open, navigate to your textures folder and here. We use the knife texture. If you wanna have preview images, simply click on this button over here. Then you’ll see what’s going on here. Click on the knife and then open image. Now we have this loaded into Blender, Lets. Go back to this tab over here. And in order to connect this image to the texture painting, go to texture, You can see the knifes already selected since we only have one texture. And very important, we wanna use a special projection mapping method And for this behind mapping. Click on stencil, And now as soon as I move my mouse above the 3D view, we have this little image down here, which we just loaded into Blender. Basically, when I move this with right, Click above my model and start painting over this everything I paint here will be projected onto the model CTRL+Z to undo this. You can see that the image is square size now and a little bit stretched. So what we have to do first is to click on image aspect. Then as you can see. This image is using the original proportions of the image. And now we can start to paint this. So let’s go to front view Numpad one. Right, click, move it to the right spot And in order to scale the image you can hit shift+right click. And then move your mouse. And with CTRL+right click, you can rotate the image if you’d like. But we don’t need that in this case. If you want to reset the transform, you simply click on this button over here. But then you also have to click on image aspect once again. So let’s scale this up. This doesn’t has to match perfectly, but it’s important that the whole model basically fits inside here. If the transparency of the image is too strong, click on display down here. And here you can increase the texture, alpha. And what I also would recommend is to enable this button. It means as soon as we paint. The image will be hidden. So let’s paint over here. And as you can see now also over here, this will be painted. Now let’s press numpad nine to switch the view to the other side. Now you can see that the image has the wrong rotation. So what we can do is simply set the X size of the texture to -1 Now we flipped the image, basically. And here I wanna use this part down here. So I also have to flip this along the Y Axis -1 Now I can move this above here and paint over this. Now let’s press numpad seven to view this from above and set the size back to positive one, And then let’s use the top view here and make the brush way smaller so that we don’t overpaint the other stuff too much again. Carefully paint over this area. Then press numpad nine to switch this to the other view. I don’t wanna use this part down here, so I simply use the same texture again and simply paint over this area again, Then. We can investigate the model. I think that’s fine. If this image confuses you, simply turn down the alpha for a second and you can see here. We still have a little spot. And we don’t always need to use these direct views. We can also stay here in a user perspective view. Then let’s increase this again and simply use a part of this texture once again and slightly paint this over here (mouse clicking). It’s so small that we won’t notice small mistakes anyways, so we don’t have to care about this that much. And the same thing I do back here. Just make sure that the size of the texture is roughly the same as we have painted on the other sides. So now let’s turn down the alpha, and now let’s take a look. I think this looks quite good. So in order to make sure that this image over here stays saved, It’s not enough to just save the blend file, which I certainly do recommend. You should do that. But you also have to save this image over here externally, because otherwise, if you now close Blender and reopen this, this image will be automatically deleted, Although Blender asks you to save the image when you close Blender, which is quite helpful. In order to save the image, click on image. Save as go to your texture folder here. You can change the name if you’d like, but I just leave it as it is, so I know what this image is about. An if you’d like down here, you can change the format of the image, but PNG is good because this is lossless without any quality loss, but we don’t need an alpha channel, a transparent background, So we just use the RGB. The red green and blue values, basically a simple colored image. So I click on that, And then I click on save as image. Now I made sure that this image what I’ve painted over here is definitely saved. All right, now, let’s texture, paint the blade of the knife. So let’s open the knife, handle here and unhide the knife blade. Then let’s switch back to object mode. Select the blade here and let’s switch back to texture paint mode. By the way, if you wanna switch between different modes, then just edit an object mode. You also can hold down CTRL+tab and hold these two buttons. Then you can see that we have all the modes listed here. And basically, all you need to do is to move your mouse in the direction of the mode. You wanna switch to? And then release Ctrl+tab? This way you can quickly switch between different modes without clicking on these buttons up here. We are now in texture, paint mode. Let’s hide the handle here. Now again! We wanna use this texture here to project paint over here. Now we can see the UV Map of the blade over here and the texture slot is also set to knife paint. And this is correct because we wanna have one texture for both the handle and the blade over here. Then again, we wanna use this texture here for texture painting. Let’s increase the alpha for the display here. Let’s take a look from the side. Numpad one shift+right click to scale this image. You can see I’ve created a separate blade up here, which is a little longer which we can easily use to texture paint here. We have to make this a bit bigger because otherwise it doesn’t cover the whole area here. So let’s simply paint over this. Then let’s press numpad nine and again set the X size to -1 to flip the image. Then let’s paint this area here. Let’s set the alpha back to zero. Now you can see we have these areas colored, but this one here and this one here is missing. What I don’t do is simply paint over here because we can maybe accidentally paint on this area here as well. So I wanna restrict the area here. So what I do? I simply switch over to edit Mode, Go to the face selection and with Alt+left click and click here and select the whole loop. You can see the triangle here is not selected. So I hold down shift. Select this one and with shift. I also select this one here. So the whole area I want to paint on. And then I can easily switch back to texture paint mode and enable this button here. Now you can see all these areas with the black wires. Here are not selected and the other stuff here is selected. You can also select stuff here in texture, paint mode, but I find it easier to do that in edit mode. That’s why I switched Now. Let’s take a look from above Numpad seven Re-enable, the texture, alpha Lets. Flip the image back. So set the X size back to positive one and simply put this blade above here and draw over this area. Then let’s do the same thing over here. Then let’s set the alpha back. Disable this button here. Now, let’s check if everything looks right. I think this looks really good. Now you can see over here. We have the texture on this map as well. And now we need to save this again because we have changed this image over here. So I click on image save. So now the knife is textured. And as soon as I switch out of texture, paint mode, you can see that the texture disappears, and that’s because this image was just projected on this object here temporarily because later on, we need to connect the image using a material to the object to see it in the final image. We wanna output from this scene here, But more about this in one of the next videos. So now let’s hide the blade of the knife as well and unhide the apple over here. Now we wanna texture. Paint the apple. So let’s select this in object mode, then with CTRL+tab. Let’s switch over to texture paint mode. Now you can see this image is still connected here to the texture paint mode. So what we need to do. We need to click the X button here. That means we won’t delete the image. That just means we remove the image from this view here. So let’s remove this. If you wanna take this back, you can simply click on this button and click on knife paint. But in this case, let’s remove this and let’s create a new one for the apple because this should have a separate texture. Click on new Lets. Call it apple paint so that we know that this is a texture, painted texture. Then again, let’s use a 2K resolution 2048. X 2048. Again. You can reduce this later on if you’d like. But we wanna have a high quality here And let’s use a simple redish-base color for the apple. We don’t need transparency here, so let’s disable Alpha and then click on, okay. Now we need to connect this new image to the texture paint mode over here for the apple. So in this tab over here, we change the knife paint image. If I click on here to the apple paint image. So before I start texture painting this, the stem of the apple is in the way when I want to texture the body of the apple. So what I do I press CTRL+tab and switch to edit Mode Left. Click somewhere to deselect everything and then by hovering my mouse above the stem, I press L and then I press H to hide this. You can see we have this left, so lets. Select this one here as well and press. H again! Now, CTRL+tab and let’s switch back to texture paint mode. And now you can see the stem is back, but as soon as I click on this button up here, the stem is gone, but now also, the whole Apple is deselected, so I simply have to press A to select everything. So now we need another image for texture painting because we don’t wanna texture. Paint the knife. So I go down here to the texture tab and first of all. Let’s click on this button to basically clean the settings down here. That doesn’t mean that I remove or delete this texture. So click on that. Click on new. Let’s call it apple and open the image from your texture folder and here we have the Apple image. And instead of left, click and then open image, you also can simply double Click on one image to open this. So now let’s get back to the texture paint settings. You can see down here. The image is selected. Now you can click in here and switch between those two images. So we keep the apple enabled Stencil and all the settings are still enabled. First of all, let’s increase the texture, alpha. So that we can see it. Then let’s reset the transform and also the image aspect. Now we have this image here and we can start texture painting. You can see this image contains the apple from below from above and different angles from the side. If I increase the alpha here, we can see it better. The Apple is a bit complicated to photograph because it has a really reflective surface and the reflection of the Apple and 3D space We wanna generate with the material so it should be inside the image. That means I gave my best to reduce the strengths of the glossy spots over here as much as I could in Photoshop. But you can still see them. But yeah, we have to deal with that here. And it won’t hurt the final result of the Apple too much. So we just have to work with that. And down here, you also have the texture for the stem. So now let’s reduce the texture alpha down here and start with the side of the apple. So maybe I tried to use the references without the yellow spot here. I think this makes this look a bit more uniform. But yeah, we just have to try it out. Working in 3D means a lot of trial and error by the way. The apple looks a bit different, but let’s just start painting. I always try to only paint the inner spot here. Not too much on the side, because then we have these flat lines and we wanna have a nice, smooth transition between all the different angles. So let’s press numpad three for the right view. Let’s use the next texture here. Make sure that on the one side you cover the area until you hit. Basically, the other texture paint. Then let’s press numpad one for the front view and numpad nine to switch the view to the other side. Now let’s use this apple down here, And now lets press three and then numpad nine to switch to the opposite side. Let’s use this one over here. Now let’s reduce the alpha value, Lets. Just check how the apple looks like. So if the Apple sometimes gets out of view, simply hit period on the numpad, then this will be focused again. Now let’s take a look from all the angles. I think this looks quite good. Now let’s take a look from above, increase the texture alpha again and let’s use the apple from above. So here we have to be really careful that we don’t paint too much on the side. Because then we have let me quickly show you. This this very harsh line over here. As you can see and this doesn’t look so good, so we only have to paint in the inner area here. I press CTRL+Z to undo this and lets. Try it again. And now let’s take a look from below Press numpad seven and then Numpad nine. So when something like this happens here as you can see, I painted too far. Let’s move back a bit and let’s grab an apple, which fits in this area here and carefully paint over this spot. So I think that’s fine. Now, Let’s reduce the texture, Alpha. And now we also need to texture the stem, But before we do that, lets. Save the image over here. So we click on image save as. We leave the name Apple paint as it is down here, We use a PNG format and RGB color and then click on save as image. Now this is saved, so we can’t lose it anymore. Then lets press CTRL+S to also save the blend file. Now let’s press Alt+H to unhide the stem. Lets press Alt+A to deselect everything and lets press L above the apple here to select only the parts down here. And you can see if I press L to select something. This is also restricted to the seams. We have set up. So if I switch over to edit mode, you can see it more clearly. If I press L over here, then it will only select this area. And this is due to the fact that the face selection is enabled. If I select Vertex selection, deselect everything and press L again. You can see it will ignore the seams here. So no matter what you choose, make sure that everything here is selected. Then let’s go back to texture paint mode. And now let’s press H to hide the apple and press A to select everything from the stem. Now let’s make the texture visible again and lets. Try to paint some of those over here. It won’t look perfect because we have quite some hard shadows on this image, but in the end, it really doesn’t matter because this stem is so small that we can’t see it that big anyway in our final scene. Just try to cover every spot of the stem here. Now we have to make sure that we don’t paint too much on the side here, because otherwise we get these sharp edges, so let’s make the brush really small. Here we have a sharp line still, so lets. Try to fix this a bit. And for the top part, we also have this little thing here. Let’s paint it to the top here. All right, that looks good to me. Let’s press Alt+H to unhide everything. Then let’s reduce the texture, Alpha, and now let’s take a look. I think this looks quite decent. Now let’s click on image and save this image once again. So now we have texture, painted both the apple and the knife. Let’s get back to layout over here and unhide everything Lets. Move the apple to the side here and also the knife once again so that we can see it. So now we basically have the foundation to add materials and textures to the rest of the scene. Don’t forget to save your file with CTRL+S. Yay, guys! Now you have a rough idea on how to use the texture paint mode in Blender.
